A new non-contact hand three-modal image acquisition system

which is suitable for security

check work attendance is designed.It solves the problems of sensing diseases and the low-recognition rate.According to the characteristics

the image sensor and lens which can obtain images under multispectral are designed and selected

and light system

regional location function and upper PC interface are designed and analyzed.The system can obtain high quality image of palm vein

palm print and palm-shape feature.It can execute online recognition fusing algorithm of three-modal feature recognition and has good man-machine interface.It has strong practicability.
